Subject: [PATCHv2 53/56] drm/omap: simplify DSI manual update code
Date: Tue, 25 Feb 2020 00:21:23 +0100	[thread overview]
Message-ID: <20200224232126.3385250-54-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20200224232126.3385250-1-sebastian.reichel@collabora.com>

Move dsi_ops into the main structure, since all other ops
are gone. Instead of checking the device type we can simply
check if dsi_ops are set.
